This invention relates to a traveling cleanmg device for stretching ordelivering mechanlsms of spinning or twisting machlnes, 1n

which a cleaning brush situated with its axle at an angle to the axle ofthe upper cylinder, automatically glides over the stretching ordelivering mechanism. l

It is known to arrange a conicalcleaning brush on two upper cylinders toclean the l0 stretching mechanism cylinders-and to guide this cleaningcylinder by a frame surrounding the same and resting on the uppercylinder. In order to prevent the frame from dropping out it extends incurved-shape around the rear upper cylinder and in order to prevent thecleaning cylinder from dropping out of the frame, the frame is providedwith two angle supports, on which the journals of the cleaning brushslide.

It is also known to make such a cleaning brush in double conical shapeand allow the same to rest with one cone on three cylinders so that itreceives; an inclined position and consequently slides longitudinallyover the cylinders of the stretching mechanism.

The known cleaning devicesk can however not be employed onthe deliverymechanism of a two-cylinder spinning machine and on drawing stretchingmechanisms.

This invention has for its .object to produce a suitable cleaning devicefor such spinning machines. With this object in View a conicalor'cylindrical cleaning brush is, according to the invention, arrangedon the 85 front upper cylinder at an mgle to its axis and mounted in aframe shiftable longitudinally on rear guides, for example on the rearuppercylinder or on the rear thread guide.

To enable this arrangement to be also em-' 40 ployed on already existingstretching and delivering mechanisms, without altering the same, theframe, if guided on the rearupper cylinder, is slightly bent, but, inorder to prevent it from dropping out, is provided at the rear with aspecial counterweight. In order to be able to clean the middle drawingupper cylinder, a special cleaning brush may at the same time beIarranged on the frame. If, however a cylindrical cleaning brush ischosen, it is mounted in a. forked'element,

oscillatable through 180 in the rear guide element, so that it can beadjusted to the most suitable position, according to the direction inwhich it is to automatically travel. The guide element or frame, in thecase of two-cylinder carriage spinning machines, slides over the knownbow-shaped thread or slub guides and for this purpose is made ininverted V-shape.

If it were desired to mount the frame orthe forked element of thecleaning brush, for example on a continuous guide rod, in the case oftwo-cylinder carriage spinning machines, this would notbe possible,because it is necessary to insert the slub between the forked thread orslub guides about every two hours. However, as already mentioned, it isdesired to enable the new cleaning device to be employed on existingarrangements without alteration.

Two embodiments of the invention are il` lustrated by way of example inthe accompanying drawings, in which:

Fig. 1 shows in side elevation the employment of a conical cleaningbrush with a fourcylinder stretching mechanism,

Fig. 2 is a front elevation of Fig. 1,

Fig. 3 is an end view, seen from the right of Fig. 4, l

Fig. 4 is a front elevation, showing the employment of a cylindricalcleaning brush with a tvo-cylinder carriage spinning mechanism an Fig. 5is a top plan view of Fi 4.

The cleaning device consists 0% a frame 1, in which the cleaning brush 2is journaled and which is moved by the cleaning cylinder over thestretching cylinders in axial direction thereto. 3, 4, 5 and 6 are thestretching cylinders in a four-cylinder stretching mechanism. Thestretching cylinders are mount-` ed vin the cylinder support 7, fixed onthe cylinder bank 8. The frames 1 is providedl with runners 9, 10 withwhich it slides on the rear stretching cylinder 6. These runners must 95be at least so long that they bear on two juxtaposed cylinders 6. Theirends are preferably bent upwards, in order to enable an easy transitionfrom one cylinder to the other. In order to 'prevent the frame fromdropping 100 olii' thecylinder 6, that is, to ensure a reliable bearing,one of the runners is provided with a counterweight 13.

A cylindrical brush 14 is mounted in the frame 1 and receives its drivefrom the inclined cleaning brush 2, for example through the intermediaryof a cord or belt drive 15, 16. This brush serves for cleaning not onlythe cleaning brush 2, but also the upper cylinders 5 and 6. Thematerial, which the brush 14 takes from the cleaning brush and the twoupper cylinders 5 and 6, is collected in an upwardly oldable comb 18,movably mounted in a frame 17, from which comb the material is easilyremoved, when the cleaning device arrivesat the end of the machine.

One of the arms carrying the weight 13 may be provided' with a brush 19,by means of which the upper portion of the carriage 20 can be cleaned.The material taken up by the brush 19 is held in a piece of cardclothing 21. A removable cover 22, lined for eX-' ample with plush onthe side directed towards the upper cylinder 6, may be arranged on thetwo runners 9 and 10 of the cleaning device for the purpose of alsoremoving dust.

The free end ofthe axle 14al of the cylindrical brush 14 may be providedwith a wheel shaped brush 25, by means owhich a further portion of thecarriage 23 and the screws mounted therein can be cleaned, whereas thedrawing cylinder 4 is kept clean by a brush 26 adjustable in height.

Finally one side portion 1a of the frame 1 may be provided with aresilient wiper 28, for the purpose of subsequently cleaning theleather-lagged stretching mechanism cylinders 3. By means of this wiperthe upper portion of the weight hook 29 will also be simultaneouslycleaned. d

When the stretching mechanism and the cleaning device are in operation,the latter moves in the direction of the arrow m (Fig. 2) it is raisedat the end of the machine from the two upper cylinders 3 and 6 andplaced on the other side of the vmachine on the stretching cylinders,after which it moves in the opposite direction, and on reaching the endof the stretching cylinders, is again placed ,on the upper cylinders andthus continually circulates.

In `the form of construction illustrated in Figs. 3 lto 5, the cleaningbrush 2 is cylindrical and is mounted in bearing slots 30 of a fork 31,and bears on the upper cylinder 3 of the stretching mechanism. Fork 31has a pin 33 mounted thereon extending nearly perpendicularly to theaxis of cylindrical brush 2. Pin 33 may be changed in position in aguiding frame 32 by 180 b v removing the fork 31 from the machine andre-inserting pin 33 with the brush and supporting structure in reversedposition. On bows 34 arranged in a common bar 35, the element 32, bentin inverted V-shape, slides like a rider,` the ends of this elementbeing slightly bent over outvardly, in order to ensure a reliabletransition from one bow 34 to the next without jamming. The pin 33,mountedin the guiding element 32 approximately perpendicularly'to theaxle of the upper cylinder 3, is bent at an angle so that the fork 31extends with the brush 2 at an angle to the axle of the upper cylinders.-When the cleaning device, consisting of the parts 2, 31, 32 and 33,reaches the end of the machine, the automatic return of the cleaningdevice is started by swinging the fork 31 withl the cleaning brush 2 outof the position shown in Fig. 5, into that indicated by the dot-dashline afi-y.'

It is evident that such a cleaning device can be employed not only onspinning and twisting machines orworking cotton, but also on machinesfor any other fibrous material.
